Fig. 4 in Phylogenetic and functional diversity of Chrysophyceae in inland waters
Fig. 4 Ternary plots showing the percentage community composition of Chrysophyceae communities in each lake (no. of OTUs per nutritional mode). Each corner of the triangle represents a nutritional mode (phototroph, mixotroph, heterotroph). The points are colored according to the values of the different environmental factors of the lakes (pH, temperature, conductivity, altitude). For results expressed as a percentage, the absolute value corresponds to 100%
